Ok there is a locked cellar in Springvale...Where the heck is the key??

So you first leave the Vault and your running around looting stuff in the hollowed out homes of springvale and as your heading over to where that one lady lives across from the school, i think right next to her house, there is a burned up place where a locked cellar door requires a key...where do you find this key? i have played through this game multiple times and am close to 100% and i have yet to find this stupid key. it is not tied to any achievments but my curiosity is driving me mad! Anyone have any idea where this key is?5 years ago

Accepted Answer

Yes, you can go there. The cellar door is unlocked by an NPC as part of the quest to get water to Megaton. The quest is called Holy Water. If you destroyed Megaton, the quest will not be available.5 years ago
